pure SNMP Replacement for SNMP - Get Processor Information

gandalf · Last edited by gandalf on Mon Apr 28, 2008 12:29 pm; edited 1 time in total

This is a pure (aka FAST) replacement of standard "SNMP - Get Processor Information".
It uses advanced SNMP Data Query XML options to provide not only the data required, but the name of the processor found!
Be prepared, that not all SNMP implementations provide data for this query. Even worse, I encountered some hosts that respond well to query indexing but don't provide the hrProcessorLoad itself.
To verify this, please run snmpwalk against .1.3.6.1.2.1.25.3.3.1.2. If no data found, please update SNMP on the target host!

I'm a problem at the creation of rra files

In graph mangement i have this :

RRDTool Command:

/usr/bin/rrdtool graph - \
--imgformat=PNG \
--start=-86400 \
--end=-300 \
--title="CAB-S03 - hrProcessorLoad |query_hrProcessorFrwID|" \
--base=1000 \
--height=120 \
--width=500 \
--alt-autoscale-max \
--lower-limit=0 \
--vertical-label="Load" \
--slope-mode \
--font TITLE:12: \
--font AXIS:8: \
--font LEGEND:10: \
--font UNIT:8: \
DEF:a="/var/www/cacti/rra/cab-s03_load_83.rrd":load:AVERAGE \
COMMENT:"CPU\: |query_hrDeviceDescr|\n" \
AREA:a#FF0000FF:"Load" \
GPRINT:a:LAST:"Current\:%8.2lf %s" \
GPRINT:a:AVERAGE:"Average\:%8.2lf %s" \
GPRINT:a:MAX:"Maximum\:%8.2lf %s\n"
RRDTool Says:

ERROR: opening '/var/www/cacti/rra/cab-s03_load_83.rrd': No such file or directory

AND in data sources i have this :

/usr/bin/rrdtool create \
/var/www/cacti/rra/cab-s03_load_83.rrd \
--step 300 \
DS:load:GAUGE:600:0:120 \
RRA:AVERAGE:0.5:1:500 \
RRA:AVERAGE:0.5:1:600 \
RRA:AVERAGE:0.5:6:700 \
RRA:AVERAGE:0.5:24:775 \
RRA:AVERAGE:0.5:288:797 \
RRA:MAX:0.5:1:500 \
RRA:MAX:0.5:1:600 \
RRA:MAX:0.5:6:700 \
RRA:MAX:0.5:24:775 \
RRA:MAX:0.5:288:797 \

Cactiuser have all rights and i have chmod 777 -r on rra, log and ressources directory.

Please help me

I've

HOST-RESOURCES-MIB::hrProcessorLoad.3 = INTEGER: 0
HOST-RESOURCES-MIB::hrProcessorLoad.4 = INTEGER: 0

I think it's good. No ?

Is this the only graph for that device? What is the devices status (from device list)? Are you running cmd.php or spine?

I have only one graph for this device and i use cmd.php
I don't know it does'nt want to create the rrd file

You didn't answer to the question about the hosts's status. I fear it is either down or undefined. This is normally a hint for a problem with downed device detection for that host. Please select SNMP as downed device detectionmethod and retry
